"Our experience with All Phases Mechanical has been excellent. On the first occasion we used APM, we lost heat during a cold snap in the middle of winter. We called in the morning and a technician arrived that afternoon and quickly determined that not only was our 20 year old furnace in need of expensive repairs (which a friend of ours in the construction industry validated), but continuing to run it would potentially result in a carbon monoxide hazard to my family. Carl gave us clear options and helped us understand benefits (rebates, no interest loans, etc.) that are available from the state to assist families in our predicament. We decided to move forward with a new furnace and Carl's team installed it the next day. On the second occasion, APM helped us our central air conditioning system. Again, Carl sent a technician who arrived promptly the same day, who determined that the air conditioning system was fine but it wasn't working properly due to faulty wiring. He quickly fixed it and was on his way - all at no charge. I can't say enough about All Phases Mechanical. If you're looking for a local company that cares about its customers (and understands that heating and cooking problems need to be addressed quickly), All Phase Mechanical is the company you should use."

"Marty installed two different units, one in my man cave and one in my house. The man cave was a single unit that heats the garage and the man cave The other unit heat for different areas of the house. Marty was able to get into spaces, but I didn’t think anybody would want to go. We’ve had them for two years now and have had no issues whatsoever."

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.
Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.
With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.
The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.
Consulting with an HVAC professional can help you determine the exact size that's right for your home.
An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.
An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
